Caption style

I want to set a style to my caption labels in a form layout but I didn’t find the way.
How can I solve it ?
Is there a way to add a style to captions ?

Caption elements have v-caption style. In your case they are inside a Form which has a v-form style. There’s also the v-formlayout between those. The captions also have some inner elements.

“.v-form .v-caption {}” should probably work in your case. See
this example

While the Book contains some information about the style names in most components, I really recommend using Firebug or some equivalent tool for browsing the DOM tree and the element styles.
